Definitions

the invention relates to a collision protection for trailed agricultural implements according to the preamble of claim 1.
Such agricultural implements are essentially today adapted to the three-point hitch of tractors of different performance classes.
the power requirement of the implements is based on the tractor power available matched that they are sometimes very high speed during their use are dragged over the surfaces to be processed.
the rotating or oscillating work organs can have obstacles in the work area, such as stones cause considerable damage to them.
the invention is therefore based on the object of a collision protection system for drawn vehicles to design agricultural implements according to the preamble of claim 1 so that the work organs in a simple manner and without externally operated adjustment mechanisms in Obstacles and work areas can avoid low impact loads the coupling device of the towing vehicle are transmitted.
the task is performed by a collision protection system for drawn agricultural vehicles Working tools with the characterizing features of claim 1 solved.
a collision protection system for drawn agricultural vehicles Working tools with the characterizing features of claim 1 solved.
Such Design of the collision protection enables the towed vehicle to automatically evade agricultural implement when hitting one in its working area Obstacle and also reduces that from the implement to the coupling eye of the towing vehicle transmitted shock loads.
FIG. 1 shows a collision safety device 1 according to the invention as part of a mower deck 2 executed agricultural implement shown, which via a coupling device 3 is adapted on a tractor 4, not shown.
the mower 2 is on the towing vehicle side via the coupling device 3 on the towing vehicle 4 and on the rear side via at least an impeller 5 supported on the floor 6.
the main frame 7 of the mower 2 is around an axis 8 running vertically to the direction of travel FR can be pivoted with a drawbar 9 connected, the invention from telescopically displaceable support profiles 10,11 is formed, which in turn by damping elements not known and known per se 12 preferably coupled together within the outer support profile 10 are.
the end of the swing arm on the towing vehicle 13 is provided with a fastening 16, not described in more detail, in which a transmission element 17, which in the simplest case can be a traction cable, is fixed, that via a on the main frame 7 attached deflection roller 18 at the other end in a likewise not described in detail Attachment 19 is fixed to the outer support profile 10.
the transmission element shown as a pull rope 17, however, can also be made by coupling linkage, which is not known and is not known per se or hydraulic elements are formed.
the outer support profile 10 has at its end on the towing vehicle as an eyelet or Bolt-shaped coupling 20 for adaptation to the towing vehicle 4 and an articulated shaft connection 21 for transmission of the drive energy from the towing vehicle 4 via a not shown, inside the support profiles 10, 11, also telescopically displaceable Drive shaft 22 to the mower 2.
the drive shaft 22 can also by not shown hydraulic components are replaced, whose energy-transmitting oil flow through flexible hydraulic hoses arranged within the support profiles 10, 11 and realizing a change in length is promoted.
the drawbar 9 with a known per se Drawbar adjustment 23 ( Figure 2) may be provided, the hydraulic cylinder 31 at one end outer support profile 10 and at the other end via damping elements 12 which are also known per se is articulated on the main frame 7 of the mower 2.
the cutter bar 25 carrying the cutting units 24 not described in more detail above Coupling member 26, the mower-side linkage is designed as an elongated hole guide 26a to connect the main frame 7 of the mower 2 so that the pivoting areas of the cutter bar 25 is limited. If a cutter bar 25 of this type meets an obstacle 27, the movement of the mower 2 due to the damping elements 12 relative to the outside Support profile 10 delayed.
the transmission element attached to the outer support profile calls 17 a pivoting movement of the rocker 13 about the axis 14 so that the mower 2 and thus the cutter bar 25 that has run up to the obstacle 27 over that at the other end of the Swing arm 13 attached and rolling on the floor 6 impeller 5 in that shown in Figure 3 Location is excavated.
this does not occur at an obstacle 27 lying in the work area the entire mower 2, but only the cutter bar 25 carrying the mowing units 24, so that the transmission member 17 is subjected to a lower tensile load.
Another embodiment, not shown, provides for the transmission element 17 to couple directly with the hydraulic cylinder 15 in such a way that when the cutter bar strikes 25 extends to an obstacle 27 of the hydraulic cylinder 15 and vice versa after Passing the obstacle 27 goes back to its original position.
Drawbar 9 or drawbar adjustment 23 also shocks the mower 2, either via the inner support profile 11 or via the drawbar adjustment 23 to the outer support profile 10 and thus transmitted via the coupling 13 to the towing vehicle 4, dampen or compensate entirely depending on their intensity.
At least one adjusting member which in the simplest case as a hydraulic cylinder that is depressurized during mower operation 30 ( Figure 4) is executed, connected to each other, there is the possibility of both support profiles 10,11 defined to move against each other, so that the length of the drawbar 9 varies can be.
the cylinder stroke of the hydraulic cylinder 30 is determined by the possible path A, which the inner support profile 11 can cover in the outer support profile 10.
